Jupiter, it's the fifth planet in our solar system and by far the biggest in the solar system. It's as well, the planet with the most moons, which is around 60. Out of the 60 moons 4 are more important than others. They are known as the Galilean Sattelites named Io, Europa, Ganymade, Callisto.
Callisto
A picture of Callisto
It's an icy moon towards the end of the solar system. It's caught in Jupiters gravitational pull, trapped with three other major moons. Callisto is unusal moon. It's crust is actually composed of ice. It is beleived that there is an ocean of salt water under it's crust. This moon surprisingly has no mountains. The surface of the moon is spotted because it is bombarded by asteroids, comets, meteors, etc. Being far away from the sun Callisto is really cold at a freezing temperature of -279°F.

Fun Facts
Callisto is about as big as Mercury.
King of Jupiter: Zeus
There is a possibility of salt water being under it's crust.
It's shell is a big conductor,conducting a electrical current.
The Surface of Callisto
Callisto has a diameter of 2,996 miles.
It takes Callisto 16.7 days to orbit jupiter.
This moon was discovered in 1610 by Galileo, a famous astronomer.
This moon was named after a nymph Zues fell in love with.
Callisto is the third largest moon in our solar system.
It produces it's own magnetic feild.
Callisto is mountainless
